if it was a case of guidance from some particular feature of this piece, I'd have thought it more likely that the colour, which could be thought of as sapphire, might be the reason for thinking W/Fs., rather than the base, which could be from any one of many makers who ground the outer area smooth with a central depression. This one could be a tad pale for W/Fs sapphire, but it's not theirs anyway.
I'm sure I've seen this general shape on various things in recent times, but now forgotten from whence they originated, so many copies of shapes, but would agree with the thought that it's probably Scandi. It does have a quality finished base,
